My recipe (realistically takes just over an hour):
Dry fry 1.5 tsp of Cumin Seeds. Remove from pan / wok / thing.
Crush the cumin seeds and add, 1.5 tsp of ground coriander, 1.5 tsp turmeric, 1/3-1/2 tsp Cardamom, 1/3 tsp of cinnamon, 1/2 tsp of ground ginger, 2 tsp of curry powerder, and mix in a mug.
Pour some oil into your wok / pan and fry 1 tsp of mustard seed untill they start popping. Add a chopped onion and your spice mix then reduce the heat so the onion cooks slowly. You need to stir to ensure the onion is covered with the intimidating amount of spices. To stop burning, add water as required.
One the onion looks cooked, add any veg you desire and cook that in the pan, covering it with the spices. I use mushrooms, summer greens and broccoli myself. Once that looks cooked, whack in a can of chopped tomatos and a splash of water, stir and allow to simmer down to the sauce thickness you desire.
Then simply add this to rice and there you go!
Its quite a long winded affair but worth the pay off. Whats cool is it allows for a lot of experimentation. You can add chillis, add meat, whatever. But once you get the hang of it, its easy peasy
